Epoch Converter
Convert Unix timestamps (Epoch time) to human-readable dates and back — with UTC, your local timezone, and any IANA zone. A live clock shows the current epoch second so you can bookmark this page as a quick reference.
Supports seconds, milliseconds, microseconds, and nanoseconds (with clear labeling), an add/subtract calculator, and copyable code snippets in common languages. Everything runs in your browser.

Frequently Asked Questions
What is Unix time / Epoch time?
Unix time (also called Epoch time) is the number of seconds since 00:00:00 UTC on 1 January 1970, not counting leap seconds. It is the standard way servers, APIs, and databases store moments in time.
What timestamp precision am I looking at (seconds vs. milliseconds)?
10-digit values are usually seconds, 13-digit values milliseconds, 16 microseconds, and 19 nanoseconds. This tool auto-detects from digit count and lets you override the unit if the guess is wrong.
What is the Year 2038 problem?
Systems that store Unix seconds in a signed 32-bit integer overflow after 2147483647 — 19 January 2038 03:14:07 UTC. JavaScript Dates are not limited this way; use the Year 2038 chip above to inspect that boundary.
How do I get the current Unix timestamp in JavaScript or Python?
See the Code snippets panel on this page — JavaScript uses Math.floor(Date.now()/1000); Python uses int(time.time()). Snippets for PHP, Java, C#, SQL, and Go are included too.
